Description

Clutch disc

Technical Field

The invention relates to a clutch plate for a friction clutch, comprising a plate-like base body with a carrier element, wherein the carrier element has an outer circumference on which a plurality of receiving regions for wing-like friction packs are arranged in a distributed manner, wherein each friction pack is connected to the carrier element, wherein each friction pack has a first friction lining and a second friction lining, wherein each first friction lining is arranged on a first friction lining carrier and each second friction lining is arranged on a second friction lining carrier, and wherein at least one spring element is arranged between each first and second friction lining carrier.

Background

Numerous embodiments have been described in the prior art for clutch plates with friction linings.

DE 2920095 a1, for example, describes a friction lining fixing device, in particular for metal or cermet friction linings of clutch plates of motor vehicles, comprising friction linings held in a carrier, which are arranged in pairs opposite one another on an elastic lining carrier, wherein each two identical lining carriers are arranged alternately with their projections facing one another, and wherein each friction lining with its carrier is connected to its assigned lining carrier by at least two fixing rivets and all fixing rivets of the two opposite lining carriers are distributed over the existing surface such that a symmetrical distribution exists with respect to a line of symmetry, in particular of the lining carriers, and no mutual overlap exists. Each lining carrier has a corresponding through-opening in the projection region of the fastening rivet opposite the lining carrier. Furthermore, the support of the friction lining also has through-openings corresponding to the lining carrier. At least one spacer rivet is arranged between the two lining carriers on the symmetry line for pretensioning the lining carriers.

The friction lining is arranged on the elastic lining carrier primarily in order that the metal or cermet friction lining is not subjected to any impacts or impacts when engaged, whereby such friction lining may be damaged at an early stage, since it is considerably less elastic than other friction linings made of, for example, resin-bonded fibers. On the other hand, such metal or cermet friction linings have the advantage of being able to transmit higher torques than other friction linings. The flexible arrangement of the friction linings can also improve the clutch's ability to be metered when engaged (dosierarkeit).

From WO 2015/024039 a1, a clutch disk for a friction clutch is known, which comprises a plate-like base body with a carrier element having an outer circumference on which a plurality of receiving regions for wing-like friction packs are arranged in a distributed manner, which friction packs are connected to the carrier element, which friction packs each have a first friction lining arranged on a first friction lining carrier, which is connected to a spring element and which is connected to the carrier element, and a second friction lining arranged on a second friction lining carrier and which is arranged between the first and the second friction lining carrier. The second friction lining carrier is directly connected to the carrier element.

Disclosure of Invention

The object on which the invention is based is to improve a clutch plate of the type mentioned at the outset, in particular to simplify its construction.

The object of the invention is achieved in the clutch disk mentioned at the outset in the following manner: a stop element is provided between the first and second friction lining carriers, on which the at least one spring element is supported and/or in which the at least one spring element is partially received, to which the first and second friction lining carriers are connected or connected, wherein the stop elements are also connected to the carrier element, wherein the first friction lining carriers are connected to the stop elements by means of in each case only one connecting element, and the spring elements are preferably designed as disk springs.

It is advantageous here that the construction of the friction assembly can be simplified in terms of design. The mass of the friction assembly and thus the overall weight of the clutch plate can also be reduced. In addition, error sources in the clutch plate manufacturing process may be reduced by reducing the number of parts of the friction assembly. In contrast to a clutch plate design with two spring metal plates, on which the friction lining carrier is mounted, the stop can be designed as a simple standard metal plate part. The support of the first friction lining in the compressed state, i.e. in the engaged state of the clutch disk, can be improved by avoiding the use of spring metal plates and preferably by using disk springs. The amount of friction available for the friction lining can thus be increased again, since the wear of the first friction lining is made more uniform by improving the contact of the first friction lining in the compressed state. Furthermore, by configuring the spring element as a disk spring, the desired spring force can be adapted to the respective application more easily than with a spring sheet metal.

In order to further improve the above-described effects and advantages of the clutch disk, it can be provided according to a variant of the clutch disk that the second friction lining carriers are each connected to the stop element by only one connecting element and/or that a spring element, in particular a disk spring, is likewise provided between the second friction lining carriers and the stop element.

According to a further embodiment of the clutch disc, a simpler mounting and dismounting of the friction linings can be achieved if the first and second friction lining carriers are each connected to the stop element by a common connecting element.

According to a preferred embodiment of the clutch plate, it can be provided that the connecting elements connecting the first friction lining carrier and the stop element each extend through a passage opening in the spring element, in particular in the disk spring. This makes it possible to achieve a flexible, pivotable mounting and elastic support of the first friction lining together with the first friction lining carrier on the stop element. The compression of the clutch on closing can thus be improved, since a more uniform contact of the entire friction surface of the first friction lining on the respective friction pair can be achieved.

In order to further improve this flexible supporting effect of the friction linings of the clutch disk, according to a further preferred embodiment of the clutch disk, it can be provided that the connecting elements connecting the second friction lining carrier and the stop element each extend through a passage opening in the spring element, in particular in the disk spring.

According to a further embodiment of the clutch plate, it can be provided that the spring element, in particular the disk spring, arranged between the first friction lining carrier and the stop element has a larger diameter than the spring element, in particular the disk spring, arranged between the second friction lining carrier and the stop element. The spring element, in particular the disk spring, can therefore be supported in different regions of the stop element, so that drag losses of clutches equipped with clutch plates can be reduced. This prevents the friction linings from adhering to the stationary clutch halves when the clutch is open.

According to a further embodiment of the clutch disc, it can be provided that the second friction lining carrier is rigidly connected to the stop element, so that only the first friction lining is supported by the spring. In this way, a clutch plate with elastic and rigid sides can be provided in a simple manner.

In order to further increase the amount of wear that can be consumed, according to one embodiment of the clutch disc, it can be provided that the first and second friction lining carriers have recesses for receiving connecting elements in the region of the connecting elements for connecting the first and second friction lining carriers to the stop elements.

In order to reduce the flexible support of the friction lining below a predetermined level or to make the friction lining yield during the joining process and thus better contact the friction pair even in friction linings without spring elements, it can be provided according to one embodiment that the stops each have a raised region which extends in the direction of the second friction lining carrier or in the direction of the first friction lining carrier.

Detailed Description

It is first pointed out that in different embodiments identical components are provided with the same reference signs or the same component names, wherein the disclosure contained in the entire description can be transferred in a meaningful manner to components having the same reference signs or the same component names. Likewise, the positional references selected in the description, such as above, below, side, etc., relate to the direct description and the figures shown and are transferred to the new position in the sense of a change of position.

Fig. 1 shows a first embodiment variant of a clutch disk 1 for a friction clutch known per se from the prior art.

The clutch plate 1 corresponds substantially to clutch plates known from the prior art. The term "substantially" means here that, as will be explained in more detail below, there are differences in the construction with respect to a friction assembly comprising a friction lining.

The clutch disk 1 therefore has a plate-like base body 2 in particular. A plurality of torsion springs 3 are arranged on or in the base body 2. In addition, a recess 4 for receiving a shaft, not shown, is formed centrally. Since this is known in principle from the prior art, reference is made to the relevant literature for details.

The base body 2 comprises a carrier element 5. The carrier element 5 is arranged at least in the region of the outer periphery 6 of the base body 2. The carrier element 5 preferably extends over the entire base body 2, i.e. from the recess 4 to the outer periphery 6. The recess 4 is therefore preferably (also) formed in the carrier element 5. Furthermore, the torsion spring 3 is preferably arranged in a corresponding receptacle in the carrier element 5. However, the carrier element 5 can also be designed as a ring element only, which is connected to the base body 2. On the other hand, the carrier element 5 can also be formed integrally with the base body 2.

On both sides of the carrier element 5, in particular sheet-like covering elements (not shown) can also be arranged at least in regions. The support element 5 is preferably made of sheet metal, in particular sheet steel.

Furthermore, the support element 5 is preferably designed in one piece, i.e. not composed of several parts.

A plurality of receiving regions 7 for receiving wing-like friction components 8 are arranged or formed distributed, in particular uniformly distributed, on the outer circumference 6 of the carrier element 5. In the example of the clutch plate 1 shown in detail in fig. 1, there are six receiving areas 7 and correspondingly six friction packs 8. This number should not be construed as limiting the invention, however, and more or fewer receiving areas 7 and friction members 8 may be present.

The friction component 8 is connected to the carrier element 5 in the receiving region 7. For this purpose, preferably holes are provided both in the receiving region 7 and also in the friction elements 8, so that the friction elements 8 are each connected to the receiving region 7 by a plurality of rivets 9 extending through the holes.

Instead of the rivet 9 or in addition thereto, the fastening, i.e. the connection of the friction assembly 8 to the receiving region 7 of the support element 5, can also be effected in a form-fitting manner, for example by bending the friction assembly 8, in particular the end region of the friction lining carrier facing the receiving region 7, by at least approximately 90 °, and inserting it into a corresponding slot-shaped receiving portion of the receiving region 7. However, the form-fit can also be formed, for example, by a dovetail-like design of the end regions of the friction elements 8, which engage in correspondingly shaped recesses in the receiving region 7.

In principle, other methods for connecting the friction arrangement 8 to the support element 5 are also possible, such as screwing, welding, etc.

Each friction pack 8 of the clutch plates 1 forms a separate pack. As can be seen from the exploded view in fig. 2 and the cross-sectional view in fig. 3, the friction assembly 8 comprises a first friction lining 10, a second friction lining 11, a first friction lining carrier 12, a second friction lining carrier 13 and at least one spring element 14. In the exemplary embodiment of the clutch disk 1 shown in fig. 1 to 3, two spring elements 14 are provided, wherein one spring element 14 is assigned to the first friction lining carrier 12 and the second spring element 14 is assigned to the second friction lining carrier 13.

Each friction pack 8 has only one first friction lining 10 and only one second friction lining 11.

Preferably, all friction packs 8 of the clutch plate 1 are of identical design. The description of the friction packs 8 can therefore be transferred to all friction packs 8 of the clutch plate 1.

The first friction lining 10 is connected to a first friction lining carrier 12, preferably sintered to the first friction lining carrier. But other attachment methods may be used. For example, the first friction lining 10 can be adhesively bonded to the first friction lining carrier 12 or adhesively bonded thereto, for example welded. Alternatively, the first friction lining 10 can be riveted (or, if appropriate, screwed) to the first friction lining carrier 12. The same applies to the method of joining the second friction lining 11 to the second friction lining carrier 13.

A stop element 15 is arranged between the first friction lining carrier 12 and the second friction lining carrier 13. The stop element 15 is in particular a sheet-metal element, preferably made of steel.

The stop element 15 has a plurality of through-openings 16 along one end face 16, by means of which the stop element 15 can be connected, in particular riveted, to the carrier element 5 in the manner described above. The end face 16 is preferably concavely curved, since it preferably follows the shape of a partial region of the circumference 6 of the carrier element 5, in which partial region the stop element 15 is arranged on the carrier element 5.

Furthermore, the stop element 15 has a spring element receptacle 17. The spring element receptacle can be designed as a recess or through-hole in the stop element 15. The spring element receptacles 17 are preferably so large that the two spring elements 14 can be partially received therein and optionally supported on the stop element 15. In the embodiment variant of the clutch plate 1 shown, the diameter 18 of the spring element receptacle 17 is greater than the (largest) diameter 19 of the spring element 14. The diameter 18 of the spring element receptacle 17 is preferably dimensioned such that the two spring elements 14 fit exactly into the through-opening 18 and can be installed (inserted) without problems.

In a preferred embodiment variant of the clutch plate 1, the two spring elements 14 are designed as disk springs. They are arranged in mirror image in the through-opening 18 of the stop element 15, so that they taper conically outward in the direction of the first or second

friction lining carrier

12, 13, as shown in fig. 2. In this embodiment variant of the clutch disk, the two disk springs therefore bear against one another in the region of the largest diameter 18 (outer diameter) in the spring element receptacle 17.

Instead of disc springs, differently configured spring elements 14, such as evolute springs, ring springs, etc., can also be used. Preferably a spring element 14 which can be arranged extending around the circumference of the through-hole 18. However, since the disk spring design is preferred, this embodiment variant will be described in detail below. But these explanations can also be transferred to clutch plates 1 with other spring elements 14.

The height of the spring element 14 in the direction of the first friction lining carrier 12 or the second friction lining carrier 13 is preferably dimensioned such that the friction lining carrier rests against the spring element 14 in any position, i.e., both in the engaged position and in the disengaged position.

Although a disk spring having a circular shape (viewed in plan view) is shown in fig. 2 and 3 and is also a preferred embodiment variant of the invention, it can also have other shapes, such as square, etc. The spring element receptacle 17 is adapted to the specific shape of the disk spring.

The friction arrangement 8 has no further spring elements apart from the spring element 14, which is embodied as a disk spring.

The first and second

friction lining carriers

12, 13 have at least one entrainment element 20 on the rear side, i.e. on the surface facing the stop element 15 (only the entrainment element 20 arranged on the first friction lining carrier 12 is visible in the figures), which extends in the direction of the stop element 15 and into a recess 21 or through-hole in the stop element corresponding to the cross-sectional shape of the entrainment element 20. Preferably, the first and second

friction lining carriers

12, 13 each have two entraining elements 20. They are preferably arranged diagonally offset from each other. The rotational locking of the first and

second friction linings

10, 11 is achieved by means of the driver element 20. For this purpose, the height 22 of the driver element 20 above the surface of the stop element 15 is dimensioned such that the driver element 20 engages in the corresponding recess 21 or through-hole in any relative position of the first and second

friction lining carriers

12, 13 with respect to the stop element 15. In addition, torque transmission can be effected via the entraining element.

The entraining element 20 can be designed as a pin which is connected to the first and second

friction lining carrier

12, 13. However, the entraining element 20 is preferably produced by deep drawing from the first and second

friction lining carrier

12, 13, i.e. is formed integrally with the first and second

friction lining carrier

12, 13.

More than two of the illustrated entraining elements, such as three, four, etc., can also be provided or embodied. In this embodiment variant, a diagonal arrangement as shown in fig. 2 is also possible, wherein in this case (every second) two entraining elements 20 can be arranged next to one another.

Furthermore, all the driver elements 20 can have the same dimensions, in particular the same diameter. However, different sizes of driver elements 20, in particular with different diameters, can also be used. The smaller entraining elements 20 can be arranged radially further inside and the larger entraining elements 20 can be arranged radially further outside on the

friction lining carriers

12, 13.

The first and second

friction lining carriers

12, 13 can each be connected individually directly to the stop element 15, for example by rivets, screws or the like. In order to be able to access these connecting elements, corresponding through-openings can be provided in the respective other friction lining and the friction lining carrier.

However, according to an embodiment of the clutch disk 1, the first and second

friction lining carriers

12, 13 are preferably connected to the stop element 15 by a common connecting element 23, which extends through the stop element 15 and the two disk springs. For this purpose, the disk springs have corresponding through-openings, as can be seen in fig. 2 and 3. In this embodiment variant, the first and second

friction lining carriers

12, 13 are indirectly connected to the stop element 15 via a connecting element 23 (i.e., to the stop element 15) in such a way that the connecting element 23 connects the first and second

friction lining carriers

12, 13 to one another and the stop element 15 and the two disk springs are held between the first and second

friction lining carriers

12, 13 via this connection, also by means of the entraining element 20.

In general, the first and, if appropriate, the second

friction lining carrier

12, 13 are each connected directly or indirectly to the stop element 15 by only one connecting element 23. Together with the spring elements 14, a "pivot point" or pivot bearing for the

friction linings

10, 11 can thus be formed, so that the friction linings can better rest against the respective friction pair.

The common connecting element 23 can be, for example, a rivet or a screw with a nut, in one or two parts.

The first friction lining 12 and the second friction lining carrier 13 are preferably made of a metal or cermet sintered material as is customary for this purpose. The friction lining can also be made of other materials, such as resin-bonded fibrous materials. These other types of friction linings are also described in detail in the relevant literature and are therefore referred to herein.

Reference is also made to the relevant literature with regard to the adhesives which can be used to form the abovementioned bonding points, since the bonding of friction linings is known per se.

The first and second

friction lining carriers

12, 13 can be made of an iron-based material, such as steel, in particular structural or hardened steel. However, brazing sheets can also be used, which are made of, for example, an iron-based material, such as steel, in particular structural or heat-treated steel.

The spring element 16 can be made of spring steel, which is particularly heat-resistant.

In the embodiment variant of the clutch plate 1 described above, the stop element 15 has a through-opening 16 for partially receiving the two disk springs. The disk spring can also be supported on an annular web which is formed on the side wall delimiting the through-opening 16. It can also be provided that the through-opening 16 is not provided, but that only a recess is provided on one or both sides, in which recess the respective disk spring part is received. It can also be provided that the disk springs are not partially received in the through-openings or recesses, but that the at least one disk spring is supported on an

outer surface

24, 25 of the stop element 15 facing the respective

friction lining carrier

12, 13. The arrangement of the disk springs shown in fig. 2 and 3 is preferred, however, since the disk springs are thereby held in place in the assembled state of the friction pack 8 and the through-openings 16 in the stop element 15 can be produced in a simple manner.

For the sake of completeness, it should be pointed out that the at least one connecting element 23 does not necessarily have to extend through the disk spring.

Fig. 4 to 8 show further and possibly separate embodiments of the clutch plate 1, in which the same reference numerals or component names as in the previous fig. 1 to 3 are used for the same components. To avoid unnecessary repetition, see or refer to the detailed description of fig. 1-3.

Fig. 4 shows a sectional view of a friction pack 8 of an embodiment of a clutch plate 1, in which the diameter of the disk spring partially arranged between the first friction lining carrier 12 and the stop element 15 is greater than the diameter of the disk spring partially arranged between the second friction lining carrier 13 and the stop element 15. For this purpose, the stop element 15 can have an annular web 26 on the side wall surrounding the through-opening 16, so that the side wall is formed with a step. The disk spring with the larger diameter rests on a step on the surface adjacent to the end face, while the smaller disk spring rests with its end face on the end face of the annular web 26, as shown in fig. 4.

Fig. 5 shows that in one embodiment variant of the clutch disk 1, only one disk spring can be assigned to the first friction lining carrier 12 (fig. 2). While the second friction lining carrier 13 is rigidly connected to the stop element 15, as shown in fig. 5. This connection can be established, for example, by a rivetless connection (verteumeln) of the at least one entraining element 20 or by rivets or the like.

Fig. 4 shows a further embodiment of the clutch disk 1, in which the first and second

friction lining carriers

12, 13 have recesses 27 for receiving the connecting elements 20, i.e., the connecting element heads 28, in the region of the connecting elements 23 for connecting the first and second

friction lining carriers

12, 13 to the stop elements 15. The depth of the recess 27 preferably corresponds to the height of the connecting element heads 28, so that each connecting element head 28 is completely received in the recess 27, as shown in fig. 4.

The stop element 15 can also have a raised region which extends in the direction of the second friction lining carrier 13 or in the direction of the first friction lining carrier 12. This raised region can be configured, for example, as an "annular wall" extending around the through-opening 16 in the stop element in order to limit the maximum possible spring travel, or be provided in the region of the securing of the second friction lining carrier 13 to the stop element 15.

Fig. 6 shows an embodiment variant of a clutch disk 1. Fig. 7 and 8 show the carrier element 5 and the friction lining carrier 12 for the clutch disk 1.

In contrast to the embodiment variant of the clutch disk according to fig. 1 to 3, in the present embodiment variant the carrier element 5 is extended to the outside in the region of the wing-like friction arrangement 8 and also forms a stop element 15 between the friction lining carriers 12, 13 (see also fig. 2). The carrier element 5 and the stop element 15 of the clutch plate 1 are thus constructed in one piece, as can best be seen from fig. 7. In other words, the stop element 15 is configured to be integrated in the carrier element 5. This has the disadvantage that the carrier element 5 becomes larger and generates more punching waste. But the riveting process for connecting the stop element 15 and the carrier element 5 is dispensed with. This in turn reduces inaccuracies based on the riveting process, which can improve component accuracy as a whole.

As can be seen from fig. 7, the carrier element 5 has a total of eight through-openings or recesses 21 for each friction pack 8, which are each grouped around the central spring element receiver 17. These recesses 21 serve to receive the entraining elements 20, as can be seen from fig. 8, each friction lining carrier having four of these entraining elements. The driver element 20 is divided here into two corner regions of the friction lining carrier 12. But such pair-wise division is not mandatory. A respective driver element 20 can also be arranged on each corner region of the friction lining carrier 12.

The driver element 20 can be designed to be deep-drawn or can be deep-drawn with a pin-back filling (hinterf ü ttern).

The clutch plate 1 is used in particular in a dry running clutch, preferably in a dry running clutch of a truck or tractor.

The examples show possible embodiment variants, it being noted here that combinations of the individual embodiment variants with one another are also possible.

For the sake of clarity, it is finally pointed out that the clutch plates are not necessarily shown to scale in order to better understand the structure of the clutch plate 1.
